Title: Method for reactive ion etching
Inventor: MATSUO SEITAROU
IPC: H01L21/3065
Filed: 1983-12-02
Abstract: PURPOSE:To enable the formation of minute patterns with a high selective property and without undercuts by drawing out ions efficiently by generating plasma at low gas pressure by utilizing electronic cyclotron resonance discharge. CONSTITUTION:A plasma flow 5 is formed by microwave electronic cyclotron resonance and because a sample carrying table 8 is arranged on a sample table 9 under the condition that it is electrically irolated from a plasma generating chamber 1, the sample carrying table 8 is charged into negative by entering of electrons. Consequently, the balance is held under such condition that the incident number of ions is in accordance with that of electrons. Namely, such electric field that reduces the speed of the electrons and accelerates the ions is produced inside tha plasma flow 5 and the ions in the plasma flow 5 are transported by that electric field so that the ions reach a sheath surface of a sample 7 efficiently. Furthermore, on a surface of the sample carrying table 8, an electric field caused by heat movement of the electrons is generated and a plasma sheath is formed and the ions in the plasma are given the directional property and the movement energy equivalent to the sum of the electric field in the electric field plasma sheath in the plasma flow and enter into the sample substrate 7.

Title: D/a converter
Inventor: ENDOU KAZUHITO
IPC: H03M1/50
Filed: 1982-12-28
Abstract: PURPOSE:To fix the intermediate point of a full scale to a ''0'' level precisely without external adjustment by finding out the quantity of level shift to be required previously before D/A conversion, and during the D/A conversion, shifting the level by said quantity in the negative direction to obtain an output. CONSTITUTION:At first, the D/A conversion of a storage circuit 11 storing a digital signal corresponding to an analog output 0V is executed. Holding voltage VREF at that time is 1/2 the full scale of an output. The voltage VREF is sampled by a switch 12 in accordance with an output from a timing controlling circuit 10 and is turned to voltage -VREF by a holding circuit 13. The voltage VREF is applied to the + input of an operational amplifier 3 and then the A/D conversion of the input signal is executed to obtain an output shifted at its level by -VREF. Therefore, the point of 1/2 the full scale coincides with 0V. At that time, it is unnecessary to use an external adjusting variable resistor.

Title: Rom evaluating device
Inventor: URABE MAKOTO
IPC: G11C29/44
Filed: 1983-12-06
Abstract: PURPOSE:To reduce greatly the waiting time for software processing and to increase the evaluating speed of a ROM by supplying the defective cell information given from a defective cell information collecting part together with the expected value information to discriminate the defective cell information and then displaying a defective cell in accordance with a chip image. CONSTITUTION:An information discriminating part 6 discriminates at a high speed the output information of an expected value information generating part 1 and transfers it to a defective cell display part 5 together with the defective cell information. The part 5 displays in a color and visually only the defective information when the expected value is set at ''1''. On the contrary, only the defective information can be displayed visually when the expected value is ''0'' by discriminatung the defective cell information with a complement of the output information of the part 1. This eliminates the overlap processing applying the software processing and then omits the arithmetic processing using the software. Thus a high-speed evaluation display is possible.

Title: Method for feeding cap for syringe needle and device using the same
Inventor: AWAZU FUMIO
IPC: A61M5/32
Filed: 1990-08-30
Abstract: PURPOSE:To enhance efficiency and save labor when feeding caps by feeding caps one by one along a guide means, and dropping each cap with its blocked end down, and turning each cap so that each cap is almost vertical with its open end down when fed to a needle. CONSTITUTION:Caps are made to fall one by one toward a guide 7 and a selective storage hole 10. The caps each of which falls with its open end down are not stopped from falling by a center bar 9 and therefore allowed to pass through the guide 7 and stored in the selective storage hole 10 and when the opening of the selective storage hole 10 is down each of the caps is further made to fall with its blocked end down. The caps each of which falls with its blocked end down are stopped from falling by the center bar 9 of the selective storage hole 10 and therefore remain in the guide 7 and when the guide 7 is shifted horizontally each of the caps is further made to fall with its blocked end down without passing through the selective storage hole 10. The caps thus aligned with their respective blocked ends down are each fed to a cannula 25 after being turned so that its open end is down.

Abstract: PURPOSE:To realize space saving without necessitating a large amount of area, by laminating plural filter element assemblies in which a metallic foil pattern such as a copper foil, etc., is formed on a dielectric sheet in a strip line type microwave filter. CONSTITUTION:An input line 4, resonance lines 6, 6, and an output line 5 are formed on the dielectric sheet 1 by conductive patterns, and the filter element assembly A is constituted of the dielectric sheet 1 and the conductive patterns, and those four filter element assemblies A ara laminated in four layers. Since an interval between the resonance lines 6, 6, or the input and output lines 4 and 5 is decided by the thickness of the dielectric sheet 1, a stable interval among the lines 4, 5, and 6 can be obtained by using the dielectric sheet 1 with required thickness. A filter characteristic between the input/output lines 4 and 5, and overlapped length among the lines 4, 5, and 6 in a thickness direc tion can be set at the 1/4 of a wavelength lambdag equivalent to the central frequency of a desired filter characteristic. Also, by thinning the thickness of the dielectric sheet 1, coupling among the lines 4, 5, and 6 can be strengthened, and insertion loss can be decreased.

Further, a light-impermeable film 204 adjacent to this mirror 203 is formed on the n-layer end face and substrate end face. At this time, the film 204 is not formed on the active layer end face 113, and a laser beam amplified and induced in the active layer 4 is emitted from the end face 113. This improves a far-field pattern of the beam.
